If you’re so inclined and mad enough to try it, you can install Google’s Android operating system on your original iPhone, iPod Touch or iPhone 3Gwith a minimum of fuss, but later iPhones like the iPhone 3GS and iPhone 4, as well as the iPad? A much stickier wicket.

Early benchmark tests of Apple’s new dual-core A5 chip featured in the iPad 2 have revealed that each processing core is actually clocked at a slower speed than the previous A4 chip, which features in the original iPad, iPhone 4, and the latest iPod touch.

Tests performed by iOSnoopsshow that overall, each of the A5’s cores runs at least 10% slower than the single core featured in Apple’s A4 chip, running at around 890 MHz in comparison to the 1 GHz A4. The speed of the A5 fluctuates depending on the applications it’s running however, with its lowest speed clocked at 861 MHz and its highest at 894 MHz.

Apple Insider has a juicy scoop from the same source who revealed the negotiations between Apple, Imagination Technologies and Samsung back in 2008 that ultimately led to the creation of the A4 CPU: Apple is reportedly building a new version of their A4 chip that will bring faster dual graphic cores to the iPhone 5 and iPad 2.

Here at Cult of Mac, we love Apple’s new A4-powered update to their “hobbyist” set-top box, the AppleTV… but all is not rosy for everyone. According to reports coming in from users, the new AppleTV might be prone to a very, very subtle skipping problem that — once seen — becomes impossible to unsee.

When Steve Jobs announced the new palm-sized AppleTV on Wednesday, replete with AirPlay-streaming functionality from your computer’s iTunes library, 720p high-def video and Netflix capability, many of us wondered if Cupertino would (or even be able) to extend the new functionality back down the line to the older, drive-based model.

Nope, says Ars Technica. An Apple spokesperson confirmed to them that there will be no software updates to bring the new AppleTV functionality to the last generation model.

To be honest, I wasn’t suspecting anything different. According to Daring Fireball’s John Gruber, even though the AppleTV doesn’t look like it is running iOS, it is… an assertion supported by the new AppleTV’s A4 CPU. The new software probably doesn’t even work on old AppleTVs, and rolling out a major software update for the obsolete model would essentially require coding the functionality from scratch.

Still, it’s disappointing. I, like many AppleTV owners, gave Apple my money for their “hobbyist” device, supporting and defending it for years even while Apple ignored it. Now that they are taking the device seriously and finally bringing the AppleTV brand up to spec, though, Apple’s quick to abandon us.
